Built For This Market
San Marcos Is Not a Copy of San Antonio
The duct work here reflects a different housing market, a different calendar and a different water table. Three local patterns shape most of the jobs we run in Hays County.
Student rental turnover sets the calendar
Texas State University drives a rental market that empties and refills in a matter of days each August, with a smaller wave in May. Those units run hard, get turned over fast, and often go years without anyone opening a return grille. If you manage rentals near campus, Sessom, or the Hunter Road corridor, the gap between move-out and move-in is the only realistic slot for duct work, and it books out early. We stage multi-unit properties by building so units come back online in sequence rather than all at once.
Older core, newer edge, two different methods
Homes around downtown, Blanco Gardens and Victory Gardens tend to run sheet metal trunks with branch takeoffs, older boots behind the registers, and modifications from past HVAC work that were never sealed properly. Registers in these houses are frequently painted or caulked into the drywall, and pulling them without cracking the wall is a skill, not a given.
The newer construction south and east of town is mostly long flex runs off large return plenums, sometimes zoned. Flex duct is easy to damage with aggressive brushing, so it gets a different tool and a lighter hand. A crew that treats both the same way will either leave the metal dirty or tear the flex. We inspect first and pick the method per material.
River corridor moisture is a real variable
San Marcos sits where two rivers meet, with a documented flood history, and properties in the low-lying parts of town carry moisture exposure that inland San Antonio neighbourhoods generally do not. Add a cooling season that keeps systems running most of the year and humidity that makes dust cling to duct interiors instead of staying loose and extractable, and you get conditions where cleaning alone is sometimes the wrong answer. Duct cleaning does not fix a moisture source. If we find one, we stop and tell you.

Everything Under One Roof
Services Available in San Marcos
Five service groups run out of one company, so a single visit can cover more than the ducts and a problem found in one system does not mean hiring a second contractor.
Air Duct Services
The full range, from inspection through to new installation, residential and commercial.
Dryer Vent Services
Long attic vent runs are common here and collect lint along the whole length, not just at the machine.
Attic Insulation
Under-insulated attics force the system to fight heat gain through the whole cooling season.
Indoor Air Quality
Equipment sized to the duct system it is going into, not sold off a shelf.
Chimney Services
A short fireplace season still leaves creosote in the flue, and caps degrade in the long off-season.
Commercial & Multi-Unit
Student housing, hotels, restaurants and offices, staged by zone and run outside customer hours.
How the Job Runs
Inspect, Isolate, Clean, Verify
Duct cleaning goes wrong in predictable ways: debris blown back into rooms, damage to registers and drywall, and no way for the customer to tell what was actually done. The sequence is built around those three risks.
-
Inspection first
We identify duct materials, locate the air handler, count supply registers and returns, and note what can be reached from the registers versus what needs another way in. This determines the method, not the other way round.
-
Access and containment
Registers come off carefully, surfaces around closet and attic equipment are protected, and the system is isolated so each trunk or branch is worked in a controlled order.
-
Source removal under negative pressure
Loosened debris is pulled toward collection instead of drifting into the room. Agitation tooling is matched to the duct type, with a Rotobrush on individual runs for deep cleaning.
-
Returns before supplies
The return side goes first so the blower is not pulling loosened material through the system. While we are there we check the filter slot and return grille for bypass gaps, which is one of the most common reasons a house gets dusty again quickly after a cleaning.
-
Verification and documentation
You get a vent count, a note on anything that could not be safely reached and why, and photographs.
One Point Of Contact
When Cleaning Is Not the Answer
Sometimes the crew opens a system and finds a problem cleaning will not solve: a disconnected flex run, torn duct insulation, damaged duct board, standing water at the condensate line, or an unsafe electrical condition near the air handler. Cleaning through any of that is malpractice.
What happens instead is that we stop, photograph it, and explain what we found in plain terms. This is where being one company matters. A duct cleaning that uncovers a collapsed flex section does not mean calling somebody else and starting over — duct repair and replacement are handled by the same team that did the inspection. You approve any change in scope before work continues, and the report goes to whoever you tell us: owner, property manager, or tenant.

Before we dispatch
It helps to know the air handler location (attic, closet or garage), whether attic access is clear, how many supply registers and return grilles you have, and anything that affects entry: gate codes, parking limits, pets, or a business's quiet hours.

FAQs
Common Questions
Do you actually serve San Marcos, or just San Antonio?
We serve both. Green Air Duct Club is based in San Antonio and dispatches across Bexar, Comal, Guadalupe and Hays counties, which includes San Marcos and the surrounding Hays County communities. San Marcos is a scheduled route, not a special trip.
How much does air duct cleaning cost in San Marcos?
Maintenance cleaning from the return duct starts at $99. Deep cleaning of individual ducts with a Rotobrush machine runs from $45 per duct. Dryer vent cleaning starts at $79. The final figure depends on your vent count, how the air handler is accessed, and what condition the ducts are in, which is why we inspect and quote before starting.
How do I know what was actually cleaned?
Because duct interiors are hidden, you get written verification: a count of the supply runs, returns and trunks that were addressed, a note on any section that could not be safely reached and why, and photographs from set points in the system.
Will duct cleaning fix a musty smell?
Sometimes. If the odour comes from dust buildup, debris sitting in the returns, or contamination in accessible duct sections, cleaning usually resolves it. If it comes from moisture at the air handler, a failing condensate line, or a building envelope problem, cleaning will not fix the source and the smell comes back. We inspect for moisture before cleaning, and if we find it we document it and tell you what needs to happen first. There is more detail in our guide to musty AC smells.
Do you have to cut holes in my ducts?
Sometimes access from the registers and the air handler is not enough to reach a main trunk or to isolate a section properly. Any opening is discussed and approved before it is made, sealed on completion, and recorded in the job documentation.
How often should I have this done?
There is no universal schedule. Systems that run most of the year, homes with pets or recent remodelling dust, and rentals with heavy turnover load faster than a lightly used house. A practical approach is to start with a clean filter after service, note the size and type, and see how quickly it loads. We put a recommendation based on what we actually saw in your system into the final documentation rather than quoting a generic interval.
Can you work around a business's opening hours?
Yes. Commercial jobs in San Marcos are commonly staged by zone and run outside customer hours, so front-of-house areas stay usable while back-of-house sections are handled first. We are available 24/7, and after-hours or staged work is planned in writing before the first visit so you know the noise windows and the sequence.
